One of the things every simmer loves most is a "live" sky, even if things can get weird sometimes.
You may spot two Easyjet flying in formation (overbooking?)
Or you may try to find a slot in a row of landing aircraft. A bit dangerous and noisy, with the TCAS screaming. Of course, the arrogant 737 succeeded to land before me, overtaking from below.

I have an old version of Picasa installed which automatically saves all the BMPs to JPG. But I think it's not downloadable anymore.
You can anyway download Irfanview, which I use since years. It has a "batch" function so you'll be able to convert all your files with just one click.

The default airports are not up to date with the ICAO charts, so you will likely find some parkings scattered around the apron with no relation with real ICAO charts. You may look for an updated afcad at the usual sites (avsim, flightsim.com, ...) and have the exact location of the stands. I've learned how to edit an airport layout using simple tools such as Airport Design Editor and try to stay up to date, at least with the airports I use most.
Or you may download the excellent charts by @allardjd from Mutley's archive here which are based on default FSX airports.

I may try to create a simple EGKC AFD for you if you want. That should be easy.
Edit: well, it took 15 mins to complete. This is the kind of work I often do for those small airfields wich are not well designed in FSX or missing at all (as EGKC). I call them BTN (better than nothing) airports! I've added the main runway, the apron entrance (the reference image from Google Maps shows some work in progress at the field), a windsock and a flatten/exclude area. Looking at the site you linked, I've added some runway markings too (which are not in the pics below).

Please extract the two files in "Addon Scenery\scenery".
Hope it is a good temporary solution.
